Agreed with the later.  It's the total environment that counts!

If you want to pay for a commercial product, you are better off obtaining
a third party prod. catalog from the 386 UNIX vendor you decide to go with.  Up
to System V R3.2, there are still some difference between different 386
unices.  So be careful!  If you buy R4, I would say you will be in very 
good shape.  R4 is bascially the same thing as SUN OS 4.1 (90+% compatible?)
and as it is from AT&T is a fairly complete package so different UNIX vendors
won't be (except SCO) contaminate it very much.
 
I would like to say that depending how much time you can afford, nowadys
with these very stable software developement packages gcc/gdb/g++/bison/perl
...., you never need to pay anything other than your time.  You get src
too!
